Mission accomplished!īut what about needing a big brain for complex tasks? In other words, these birds could categorise both tools as a “toolset” and use it accordingly. Though only five of the ten birds made it through the earlier experiments, four of those that did tended to transport both tools in one go, in anticipation of needing them to open the two-tool box.
They were tested in various ways to examine their flexibility and innovation, but the pièce de resistance came when reaching the box with the tools required additional movement, including climbing a ladder, and horizontal and vertical flight. The birds, initially ten in total, had to extract cashews from boxes that required either one or two tool types. Inspired by the toolsets chimpanzees use and transport in the wild for extracting termites from the ground, the authors of the study designed clever experiments to test Goffin’s cockatoos under similar circumstances. This panel of photos shows Figaro the cockatoo flying with two tools towards a box with a cashew. They’ve been confirmed as the third species that can not only use tools, but can carry toolsets in anticipation of needing them later on. This is precisely what Goffin’s cockatoos have now been shown to do (albeit in a captive setting). They must have been thinking it through from start to finish! Researchers finally solved this when they observed chimpanzees not only carrying their toolsets with them, but doing this flexibly and according to the exact problems they faced. Anticipating problemsĪn initial stumbling block in interpreting chimps’ use of toolsets was that nobody could show whether they visualised a collection of small tasks as one problem, or used single tools to solve separate problems. This requires similar brain power to a chimp’s method of using multiple tools when fishing for termites. The 2021 study of wild Goffin’s cockatoos was particularly significant as it showed the birds’ tools were similar in complexity to those made by chimps, meaning their cognitive skills could be directly compared.Ī small number of Goffin’s cockatoos were seen crafting a set of tools designed for three different purposes – wedging, cutting, and spooning – and using them sequentially to access seeds in fruits. They grasp the drumstick or seedpod in the left foot and beat it against a hollow trunk in a rhythmic performance, with all the hallmarks of human instrumental music. Males in northern Australia “manufacture” drumsticks and seedpod tools to use during their complex mating displays. They’re known to be highly intelligent creatures, yet they’ve rarely been observed using tools in the wild.Ĭuriously, the only parrot species known to use tools regularly in the wild is Australia’s own palm cockatoo, which uses them in a very unusual way.
Parrots have proven to be something of an enigma. Goffin’s cockatoos are endemic to the Tanimbar Islands in Indonesia. And in research published this week, researchers have shown Goffin’s cockatoos can also take the next leap of logic, by carrying a set of tools they’ll need for a future task. They were also thought to be the only animals that carried toolsets, in anticipation of needing them later.Ī third species joined the exclusive club of toolset makers in 2021, when scientists in Indonesia saw wild Goffin’s cockatoos using three distinct types of tools to extract seeds from fruit. They were considered the only species that used “toolsets”, wherein a collection of different tools is used to achieve a task.
Until recently, humans and chimps stood out among tool-using species.
Kinds of cockatoos how to#
It’s often thought a big brain is needed to understand the properties of objects, how to finely manipulate them, and how to teach this to other members of a species. Tool use among non-human animals is hotly debated. However, the notion that tool use is an exclusively human trait was shattered in the 1960s when Jane Goodall observed our closest living relatives, chimpanzees, retrieving termites from holes with stripped twigs. From pocket knives to smart phones, humans keep inventing ever-more-sophisticated tools.
